Abstract

A method (900) of and wireless communications unit (800) for effecting a handoff from a first Internet Protocol (IP) connection(221) to a second IP connection (331) for a time critical communication is disclosed. The method includes communicating (905) between a first wireless station ( 219) and a second station (331) using the first IP connection and a first IP address (223) for the first wireless station; setting up (907) the second IP connection with a second IP address for the first wireless station, the first IP connection being a primary connection and the second IP connection being a secondary connection; determining (915) that the second IP connection should be the primary connection; and changing (917) the second IP connection to the primary connection by informing the second station that the second IP address is the primary address using stream control transmission protocol (SCTP) messages.
